ICON Billet Upper Control Arms

2021–2023 Ram 1500 TRX

218561DJ

Overview:

The ICON Billet Upper Control Arm DJ Pro Kit is a premium suspension upgrade designed specifically for the 2021 to 2023 Ram 1500 TRX. This kit features ICON’s innovative Delta Joint PRO, a high-performance articulation joint that blends the durability of factory-style ball joints with the strength and articulation range of motorsports-grade uniballs. Engineered to enhance suspension travel and maintain precise alignment, this kit is ideal for off-road enthusiasts and performance drivers seeking improved suspension geometry and reliability under extreme conditions.

With a focus on durability and articulation, the Delta Joint PRO allows for a full 90 degrees of bind-free movement, providing a 14% increase in range of motion compared to ICON’s original Delta Joint. This ensures maximum suspension travel without compromising strength or longevity, making it perfect for lifted trucks running larger tires and tackling rugged terrain.

Key Features:

The ICON Billet UCA DJ Pro Kit combines advanced engineering and robust materials to deliver superior performance and durability:

• Patented Delta Joint PRO (U.S. Pat. 10,731,700) offers maximum articulation without binding
• 56% larger bearing surface than standard Delta Joint for enhanced strength and longevity
• Full 90 degrees of articulation for improved suspension travel and bind-free movement
• Chromoly ball and shaft with bearing surface hardened to Rockwell C 55 for extreme durability
• Replaceable graphite-impregnated sintered metal races machined to precise tolerances
• Redesigned lubrication system with efficient grease channels sealed within bearing caps
• CNC machined 6061 billet aluminum construction with satin anodized finish for corrosion resistance
• PTFE-lined rod ends and FK rod ends at chassis pivots for strength and smooth operation
• Quick, on-vehicle adjustment for caster and camber using ICON’s Double Adjuster System
• Built-in O-ring sealed dust cover cap to protect internal components from contaminants

Construction & Design:

Each upper control arm is precision CNC machined from high-grade 6061 aluminum billet, providing an excellent strength-to-weight ratio and superior corrosion resistance. The Delta Joint PRO features a chromoly steel ball and shaft with a hardened bearing surface rated at Rockwell C 55, ensuring exceptional wear resistance and longevity under heavy loads and off-road abuse.

The replaceable bearing races are crafted from graphite-impregnated sintered metal, delivering a smooth, metal-to-metal interface that minimizes friction and enhances durability. ICON’s advanced lubrication channels distribute grease efficiently within the joint without compromising the integrity of the sealed dust cover, extending service intervals and reducing maintenance.

Installation & Fitment:

This kit is designed as a direct fit replacement for the Ram 1500 TRX models from 2021 through 2023. Installation is straightforward for experienced technicians and suspension specialists, with quick and precise adjustments available on the vehicle to dial in caster and camber settings using ICON’s patented Double Adjuster System. While the kit supports 35" x 12.50" tires without modification, larger tires may require fender trimming or additional suspension modifications to ensure proper clearance and performance.

What's Included:

• Pair of ICON Billet Upper Control Arms with Delta Joint PRO
• FK rod ends for chassis pivots
• Adjuster hardware for caster and camber alignment
• Sealed dust cover caps
• Installation instructions

Ideal For:

This upper control arm kit is ideal for Ram 1500 TRX owners who demand enhanced suspension articulation, durability, and alignment correction for lifted trucks. It suits off-road enthusiasts, performance drivers, and anyone upgrading to larger tires who require reliable, bind-free suspension movement and improved handling characteristics under extreme conditions.
